    Hello Bigzmey,

    I understand.

    Astronomik makes no marketing, no advs, and has no David Knisely.
    But we can ring up Gerd Neumann who designs and makes the filters, and we have a nice and helpful chat.

    It goes similarly as with the Astrodon U.S.
    Before spending the $400 on the extra narrow band OIII filter, I have mailed Don Goldman, asking a couple of questions. He has designed these extra narrow band filters.
    Don makes no marketing in Germany, I have purchased that OIII filter in France.

    Baader is more visible on the markets, and Thomas Baader himself is another filter freak and filter technology freak.
    No problem to mail his boys, or to meet Thomas Baader somewhere.

    What counts as always, is the level of performance of optics you are looking for, the technology standard used in the manufacturing, who stands behind, and what you are ready to pay.

    Best,

    JG

    Hi JG.
    From the sampling I had Astronomik is at the top. However, now days I prefer to buy my equipment used for many reasons (stretch my $$, help fellow astronomers, prolong life of the equipment, etc.) and they just don't come out on US classifieds as often as Lumincon or Baader.

    Hello Bigzmey,

    that's the correct approach of yours!
    As I have now more time to check out the pre-owned items offers, I am doing the same, and on the same reasons.
    Regarding the Astronomik and Baader filters, I have not seen them on the 2nd hand markets, whatever reason might be.

    Since some time, I have started to repurpose the pre-owned microscopy filters for the astronomy, and will report asap.
    So, it is not just about my repurposing the microscopy EPs, ha, ha.

    Best,

    The Baader Neodymium's are great filters indeed. The Contrast Booster is probably the best planetary filter I have personally used. And as previously noted, a great doubles filter as well.

    Concerning the Atronomik line: The new Bandmate II line of filters by Televue is actually manufactured by Astronomik. The Oiii and the H-Beta being identical in band-pass transmission between the brands. The TeleVue version of the UHC cuts the red spectral transmission, as where the Astronomik passes it. I haven't personally tested one, but the TeleVue version reportedly renders more pinpoint stars and eliminated the "bloat" frequently caused by the red band-pass.

    As to browsing the used market: My Ep case(s) are filled with hand me downs I've acquired on the pre-owned market.

    Thanks Frankie, I will keep an eye for TV Bandmate II.
